Spiral Vane Flame Augmenter for Stable Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flame-producing devices, such as vortex gas lamps and fire tornado lamps, face challenges in augmenting the height of the flame while maintaining its stability, as they constrain the flame to a certain height and shape, making it difficult to achieve a longer, swirling flame.
Innovation Solution
A device featuring a fluid-inducing assembly with a flow-diverting mechanism and a shield, where external air is induced through spiral passages, swirled, and accelerated to enhance the flame's height, maintaining its stability by positioning the flow-intake end lower than the flame and using a shield to direct and swirl the air.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If air flows through ports in a direction perpendicular to the combustible gas flow direction, then the flame shape is stably maintained, but the flame height cannot be augmented
Solution Approach 1:
The patent employs a spiral-shaped passage instead of straight or simple curved paths. The spiral configuration creates a swirling flow pattern that generates centrifugal force, which stabilizes the flame while allowing it to extend vertically. The curved spiral path transforms the perpendicular airflow into a rotational flow that supports taller flame structures.
Solution Approach 2:
The patent utilizes fluid dynamics principles by designing a passage that induces swirling motion in the air-gas mixture. The spiral passage creates a vortex flow that generates centrifugal force to stabilize the flame vertically, while the controlled airflow through the passage allows the flame to achieve greater height without sacrificing stability.
2Length of moving object
If the flame is constrained to a certain height to maintain stable shape, then the flame shape is stable, but the flame height is limited
Solution Approach 1:
The spiral passage design creates a self-stabilizing vortex flow that naturally maintains flame stability while allowing height extension. The centrifugal force generated by the spiral configuration provides inherent stabilization, eliminating the need for additional control mechanisms and making the system easy to operate while achieving taller flames.
Solution Approach 2:
The spiral passage structure enables the flame to self-stabilize through the centrifugal force generated by the swirling flow. The system automatically maintains stable flame shape and appropriate height through the inherent fluid dynamics of the spiral configuration, without requiring external control or adjustment mechanisms.

AI summary
A device for producing a stable and augmented flame includes a fluid-inducing assembly and a shield. The fluid-inducing assembly includes a flow-diverting mechanism defining a flow-intake end and a flow-accelerating end and includes a plurality of vanes extending from the flow-intake end to the flow-accelerating end. The plurality of vanes is circumferentially disposed and spaced from one another. Furthermore, two vanes include a space defined therebetween, and the space defines a passage which is spiral-shaped. The flow-diverting mechanism further includes a covering member with an enclosed circumferential edge circumferentially surrounded. Thus, each vane in the flow-accelerating end is encircled by the covering member, and each vane in the flow-intake end is exposed to outside and not covered by the covering member. In addition, the shield is hollow and is disposed above the fluid-inducing assembly.
